A prompt gains value when it can be tested and repeated.

A library does not collect as many instructions as possible. It keeps the building blocks for recurring work that have a clear purpose, variables and a test.

The card for a tested prompt building block

A good prompt is rarely one brilliant sentence. More often, it is a small working instruction that has proved useful in daily work: it has a clear purpose, the right material, an expected form and a check. Once the same task returns, it is worth turning that instruction into a building block—not to automate conversations, but to make quality repeatable.

01 · PurposeWhich recurring task does this block solve?

02 · VariablesWhat must be visibly replaced for the concrete case?

03 · CheckHow do you know the outcome is genuinely usable?

The building-block card

Name, purpose, inputs, instruction, check criterion, boundary and version turn a good phrasing into a usable working tool.

THE TWO-CASE TEST

Test the same block with a normal and a difficult case. Revise only what the comparison actually reveals as a gap.
